Type vernata Harr. 



Tongue wanting ; palpi very short ; clypeus very broad, untufted, 

 scaled ; antennae of % with segments swollen, obtusely or bluntly 

 dentate, with a fascicle of hairs on each protuberance ; those of 9 

 ciliate filiform ; thorax of S with low posterior tuft, 9 untufted. 

 Abdomen untufted, in both sexes with segments armed with two 

 rows of spines turned backward, somewhat curved. In 9 thorax 

 and abdomen enlarged, scarcely separated, somewhat vermiform ; fore 

 tibiae unarmed, hind tibiae with two pairs of spurs; fore wings of 1 

 12 veins, vein 1 with long furcation at base, discal cell long, G widely 

 separate from 7, 10 and 11 from cell, accessory cell large; hind 

 wings 8 veins, 3 widely separate from 4, 5 much nearer 4 than mid- 

 dle of cell being in this respect quite noctuiform, 6 and 7 separate, 

 8 anastomosing with cell to beyond middle ; 9 wingless ; larva with 

 10 legs. 



The genus is remarkable for the spinulation of the abdomen in 

 which respect it agrees with only one or two genera in the Ennominge. 

 It is closely allied to Almphila Hiib.
